Container Light Steel House Materials

The main materials for container light steel houses include steel, enclosure panels, door and window materials, and auxiliary materials, as follows:

Steel

Steel is the core structural material for container light steel houses, requiring high strength and corrosion resistance. Common types of steel include hot-dip galvanized cold-formed steel, channel steel, angle steel, and steel plates. The hot-dip galvanizing process covers the steel surface with a zinc layer, forming a dense protective layer that effectively isolates moisture and oxygen, preventing steel corrosion and extending the house's service life. Channel steel and angle steel are mostly used for frame construction, with their cross-sectional shapes enhancing structural stability; steel plates are used to make wall or roof purlins, processed into specific shapes through cold-forming processes to meet different design requirements.

Enclosure Panels

Enclosure panels directly affect the house's thermal insulation, sound insulation, and fire resistance. Common panels include rock wool sandwich panels, glass wool sandwich panels, polyurethane sandwich panels, and metal panels. Rock wool and glass wool sandwich panels use inorganic fibers as core materials, offering excellent fire resistance (with a fire endurance of up to 1-2 hours) and thermal insulation (with a thermal conductivity of approximately 0.03-0.04 W/(m·K)), suitable for scenarios with high fire safety requirements; polyurethane sandwich panels use organic polymer materials as core materials, with low density and high strength, but slightly weaker fire resistance, mostly used in temporary buildings. Metal panels (such as galvanized steel plates and aluminum plates) are often used as outer cladding panels, combined with core materials through cold-forming processes to form an integrated structure, providing both protection and decoration functions.

Door and Window Materials

Door and window materials need to meet lighting, ventilation, and sealing requirements. Aluminum alloy is the mainstream material for door and window frames, with low density and high strength, and its surface can form a protective layer through anodizing or spraying processes, offering strong corrosion resistance. Aluminum alloy doors and windows mostly adopt insulated glass structures, with inert gases (such as argon) filled between the glass panes, significantly reducing the thermal conductivity coefficient and improving thermal insulation performance. In addition, some high-end projects use broken-bridge aluminum alloy doors and windows, which further block thermal bridges by embedding thermal insulation strips in the profiles, enhancing energy efficiency.

Auxiliary Materials

Auxiliary materials include connectors, sealing materials, and flooring materials, etc. Connectors (such as bolts and rivets) need to have high strength and corrosion resistance to ensure stable structural connections; sealing materials (such as silicone sealants and EPDM rubber strips) are used to fill gaps between panels, preventing rainwater leakage and air infiltration; flooring materials are selected according to the usage scenario, with cement fiber boards or steel-wood composite floors mostly used in temporary buildings, and tiles or wooden floors possibly used in long-term usage scenarios.
